摘要

The body (1) comprises a massive resonance unit and at least one hollow resonance unit. The massive resonance unit is formed by a base plate (2) and the resonance unit is formed by at least one tone chamber (3). At least one tone chamber (3) is defined by either the inner surface of at least one sounding plate (4,5) and the inner walls of at least one opening (7) and / or at least one cutout and / or at least one recess (9) formed in the base plate. (2) or the inner surface of at least one sounding plate (4,5), the inner surface and the inner walls of at least one opening (7) and / or at least one recess and / or at least one recess (9) formed in the base plate (2) . At the point of mutual contact of the at least one sounding plate (4,5) and the base plate (2), the peripheral edge (10) of the inner surface of the at least one sounding plate (4,5) is closer to the opposite wall of the body (1) than the peripheral edge (11). 13) an opening (7) and / or a recess and / or recess (9). Alternatively, there is within the at least one tone chamber (3) a block which may be part of the base plate (2). According to other alternatives, a recess formed in the base plate (2) or a profile (16) provided inside the tone chamber (3), preferably provided in the groove (17), is located opposite the peripheral edge (10) of the inner surface of the baffle plate (4,5). or a recess (15) is formed opposite the circumferential edge (13) in the soundboard (4).
